Data multiplexing apparatus, data multiplexing method, and transmission apparatus

Abstract

A data multiplexing apparatus (1) includes: a packet number obtainment unit (109) for obtaining the total number of packets included in one block on a private data packet stream inputted into a channel buffer (101); an address obtainment unit (110) for obtaining the address of the starting packet in each private data block; a null packet detection unit (111) for detecting null packets when a multiplexed packet stream of data other than the private data is outputted from the channel buffer (101); and a packet replacement unit (112) for replacing the multiplexed null packets detected by the null packet detection unit (111) with the private data packets and outputting the multiplexed packet stream.

AI Technical Summary

Benefits of technology

The data multiplexing device and method can prevent delays for certain packets without affecting others. This helps improve overall efficiency and performance.

Problems solved by technology

The technical problem addressed in this patent is reducing delays in transmitting multiplexed packet streams through a data multiplexing apparatus without compromizing privacy and performance requirements. Previous methods have resulted in long delays due to issues with latency in processing and multiplexing packet buffers, leading to impact users' experience and slow downstream distribution rates. This new approach provides a solution by introducing a data multiplexing apparatus capable of efficiently removing null pointers and replacing them with private data packets.
